Scores on the twenty aptitude and achievement tests administered in July 1948 to the incoming class at the U.S. Naval Postgraduate School have been related to the quality-point ratios of the officers in this class for their entire first year. Charts have been prepared showing for each of four score intervals on each test the percentage of students having such test scores who earned quality- point ratios above 2.00. Also, product-moment coefficients of correlation between scores on each test and the criterion of quality-point ratios have been computed. Examination of the charts and consideration of the correlations presented in this report reveal that the tests which showed high relationships with the academic grades were those in mathematical aptitude and mathematical achievement, engineering, reading comprehension, and physics. It was concluded that a very promising start has been made on the task of developing a battery of tests suitable for use as part of the means of selecting students for the Naval Postgraduate School.
